Patch node

A Patch node represents a software patch in your network environment and is linked to any Host node which contains it.

You will only find Patch nodes linked to operating systems which recognize patches. Currently only three operating systems that BMC Discovery models have the concept of a patch; Solaris, HPUX and Windows.

Patch node lifecycle

The following section describes the scenarios in which a Patch is created, updated or destroyed. Patch nodes are identical in behavior to Package nodes, see Package-node.

Creation

Patch nodes are created when they are first detected on a host. The key of a Patch node consists of two critical properties; name and OS information. Therefore, Patch nodes are shared by all Host nodes with the same patch installed.

Update

A Patch node is never updated because its key consists of two critical properties and a change to either of them will result in a new Patch node being created.

Removal

To remove a Patch node manually, find the necessary Patch node, select it in the list and pick Destroy from the Actions list.
